Hi, I want the option in my texture loader to load custom mipmap textures rather than letting OpenGL build them for me (glGenerateMipmapEXT or whatever) So if i have an image, and N mipmap images (created in photoshop or whatever), how do I load that as a texture in OpenGL? Also, assuming my first question is possible, do subsequent mipmaps need to be half the width/height of the next larger one, and can i control the distances from the viewer at which the mipmaps are used in the renderer? Thanks in advance, Hybrid

Like the first mipmap level, you load every mipmap level with glTexImage. And yes, lower mipmap levels must be half the size of upper mipmap levels. Be aware of the rules regarding odd sizes; you must round the size downwards of the previous size was an odd number.

Thanks for the help guys that's sorted me out! Can't believe I'd never relaised what the "level" parameter was for!

And regarding DDS textures.. I'll take a look into it ;)

Thanks again,
Hybrid
